SQL & PL/SQL :: Conditional Insert With Multiple Subqueries
Oct 9, 2012
We have multiple environments and our dev and UAT ones are now different from staging and live (I know, but I am not in a position to get this fixed). I have a set of updates that need to go through to live and in some cases they reference rows that do not exist in the UAT environment, and yet they have to (rigid, dumb process) go through that environment.
Basically, the insert I need to do takes info from two tables and does an insert into a third. That target table has a not null constraint on the affected fields, so the insert fails, quite rightly.
There's lots of info available on how to do conditional inserts with single sub-queries, using DUAL and EXISTS (or rather NOT EXISTS, but that's easy to swap), but those don't seem to easily translate for this one.
The sql that works when everything exists is:
insert into wmcontent.wm_manda_corpserv_companies
(wm_manda_company_code, wm_corp_company_code)
values
( (select wm_company_code from wmcontent.wm_m_and_a_company where wm_company = 'SW'), (select min(oid) from wmcontent.wx_category where content_type = 2 and name = 'SW') );
In desperation I even tried using "log errors reject limit unlimited" but, no doubt due to my misunderstanding of how that works, I ended up getting the error "ORA-06550: line 38, column 1: PL/SQL: ORA-00972: identifier is too long" as a result.

I'm trying to insert only a few columns (not all of them) from temp_ioi_010209 into mtl_system_items_interface. Both of these tables have more columns than just the 7 I'm specifying but everything I found under INSERT ALL here makes me think I'm doing it right. According to the DESCRIBE of mtl_system_items_interface the only non-nullable column is set_process_id and I'm specifying that one...
Why I'm getting the error "ORA-00947: not enough values"?
INSERT ALL INTO mtl_system_items_interface
VALUES
(process_flag,
transaction_type,
set_process_id,
[code].......

In mys store procedure I am using a subquery with INNER JOIN. This subquery calls a user defined function which takes main query fields as parameter values. But i am facing issue for accessing main query fields. my query is like below:
SELECT
ID, Name, sub.Desc, sub.Date
FROM MainTable main
INNER JOIN
(
SELECT * FROM RMF_GetData(main.ID)
) sub
ON main.ContactID = sub.ContactID
I need data from a function in a table format based on some case conditions. Hence i need to join it with main table. But here oracle gives error as "invalid identifier" for main.ID parameter.

i was just working on one of my SQL assignments from my database management course, and thus far, this is the first that I just can't figure out. The question is:
Quote: Increase the credit limit of any customer who has any order that exceeds their credit limit. The new credit limit should be set to their maximim order amount plus $1,000. This must be done in 1 SQL statement
The bolded part is what I'm having trouble with.
What I have thus far:
UPDATE Customers
SET CreditLimit = 1000 + (SELECT MAX(Amount) FROM Orders, Customers WHERE Cust = CustNum)
WHERE CustNum IN (
SELECT Cust
FROM Orders
WHERE Cust = CustNum
AND CreditLimit < Amount);
So there's two tables that I'll be working with, Customers (the table I'm updating), and Orders (the table where the order amount is found). With the code I have so far, it does seem to be updating the correct tables at the very least, but not with the correct values. It's essentially updating the CreditLimit column with the new value of 1000 + the maximum amount in the order table, which is very close to what I want it to do, but I want it to be 1000 + the maximum amount for that specific customer.
CustNum is the primary key for the Customers table, and Cust is the foreign key that links each together.
(about the formatting, it looked much prettier in SQL Worksheet Plus)

I would like to pass my 1Z0-047 certification, but I don't understand the limitation on the scalar subqueries, especially for the having clause.
Here is my scalar subquery because it returns only one value.
CODEselect avg(list_price)
from product_information
I use it in a having clause as a scalar subquery and it works
CODEselect status ,avg(list_price)
from product_information
group by status
having (select avg(list_price)
from product_information)
>= avg(list_price);
but it is documented that it can't works :
QUOTE There are also important restrictions on scalar subqueries. Scalar subqueries can�t be used for:
Default values for columns
RETURNING clauses
Hash expressions for clusters
Functional index expressions
CHECK constraints on columns
WHEN condition of triggers
GROUP BY and HAVING clauses
START WITH and CONNECT BY clauses
I probably don't understand the limitation .

I'm trying to create a query based upon an IAL (I'm using IFS). The IAL contains sales, grouped by month, for each customer. The output of the query should be as follows:
Cust_No
Spend in Month
Spend in Quarter
Spend in Year
My first thought was to have three subqueries, summing data from the IAL where the month of sale was last month, in the last 3 months, and in the last 12 months. Is this the right way to go? And what is the syntax?

I am trying to insert records in multiple tables. I know how to view data using joinig, but unable to understand how to insert records in multiple tables using Joining. I searched it on net, but didn't find much. I have also tried to write a code, but it is not working, I have seen some examples on different websites where people are using SELECT in INSERT statement for joining. What is the correct Syntax to INSERT record in Multiple tables.
Insert into library_users, library_users_info
(library_users.username, library_users.password, library_users_info.address, library_users_info.phone_no) VALUES (...)

We get data from our customers which we load into temporary tables.The goal is to consolidate this data into one single table.
Following are the rules:
1) final table should have all the columns from all the tables. If there are common column(s) then add only one column with that name.
2) the join would be based on all the common columns
3) if there is a common row, we merge the row into one (example, the row with DOMAIN = ACME.COM)
4) There could be 'N' number of tables
Following is the most realistic data.
1) T1/T2/T3 has the sample data which cover most of our test cases
2) We are expected to transform the data from T1/T2/T3 as depicted in table T4.
3) we might have more than 3 tables in our production environment, so the query should work for N tables.
4) I have given the explanation of how each row should be derived to be inserted in T4
5) the only information we have to work with is the TABLE_NAME(s) and its metadata from USER_TAB_COLUMNS
DROP TABLE T1;
DROP TABLE T2;
DROP TABLE T3;
DROP TABLE T4;
[code].....
Explanation for each row:
row1) This row comes from T1 and T2 (not T3 because HOSTNAME would not match)
row2) This row comes from T1 and T3 (not T2 because HOSTNAME would not match)
row3) This row comes from T1 and T3
row4) This row comes from T2 and T3
row5) This row comes from T3

I have a temp table and want to insert that data into 2 tables. In both of my tables i have a sequence column but in my second table its a foreign key to the main table
up_query="INSERT INTO AFFILIATE (FNAME,LNAME,EMAIL,PHONE,ORG,ADDRESS1,ADDRESS2,COUNTY_ID,AFF_ID)
Select a.FNAME, a.LNAME,a.EMAIL,a.PHONE, a.ORG, a.ADDRESS1, a.ADDRESS2,C.COUNTY_ID,'AF'||aff_seq.nextval

left outer join DEPT D ON (UPPER(A.DEPT)=UPPER(D.DNAME))
left outer join CAMPUS C ON (UPPER(A.CAMPUS)=UPPER(C.CPNAME))";
However in my test4 table its inserting the aff_seq.currval for all records. Its not incrementing as in the affiliate table.

I'm writing a Procedure which Updates or Inserts data in Multiple tables. Selected fields of 10 tables need to be updated or Inserted. For this I created a table which comprises of fields related to all 10 tables. Then I write Procedure. Under this I create a Cursor which uploads the data from the newly created table which contains different fields of 10 tables. Then I write Update and Insert statements one by one for all 10 tables.
Sample Procedure below.
-------------------------------------------
Create or replace procedure p_proc as
spidm spriden.spriden_pidm%type;
cursor mycur is select * from mytable;
begin
for rec in mycur
[code]......
----------
Note: I created table on my server because data is coming from different server. They will upload the data in the table from there I pick and update the tables. Is updating or Inserting data in different tables one by one is correct?

I have two different java process trying to insert in the same time in the same table for the same trade. The structure of the table Report is
create table report
( TRADE_ID NUMBER,
VERSION NUMBER,
MESSAGE_TIME TIMESTAMP)
There is a unique key on (TRADE_ID and VERSION) So if a new trade_id is inserted, the version is set to 1 and the second becomes 2 and so on. The version is calculated as last version of the trade_id ie. version + 1. It was woking fine till a new Java process was build that fired inserts through ten different java instances at the same time resulting in unique key error. So in detail what is hapenning is if three records of trade_id's comes in at the same time it should allocate versions in a first come first serve basis and there should be three versions of trade id 1,2 and 3. Now due to the multiple instances they all seems to get fired at once and all ending up with version one and thus resulting in unique key constrain error while trying to insert into the table.

how to do a conditional range in a query. For example, I have two tables:
table A:
a1 char(1)
a2 char(1)
table B:
b1 char(1)
b2 int
In my query I want to range on a different value in the b2 field depending on what is in the fields in the A table. For example, if the a1 field is Y, I want to look up the record in B with a b2=20. If a2 is Y, I want to look up b2=5. Otherwise I want to look up b2=1. I attempted the following:
select b1 from b, a where b2=(if a1='Y' then 20; elsif a2='Y' then 5; else 1)
but that doesn't work.

I'd like to select one of two fields from a table, based on which of them is greater for that row.
e.g. For every row in JOINING_TBL, I'd like to select either JOINING_DATE or REJOINING_DATE, whichever is greater. I do dream about being able to use a Java-like ternary operator in here, something like this:-
SELECT (JOINING_DATE>REJOINING_DATE?JOINING_DATE:REJOINING_DATE) FROM JOINING_TBL
However, I understand(through other fora) that this can't be used in here.

I'd like to have a conditional that only gets the next value from a sequence is the current (or supplied) value is null.
Here are some trivial examples:
CREATE SEQUENCE ts
MINVALUE 1
START WITH 1
INCREMENT BY 1;
SELECT ts.NEXTVAL FROM DUAL;
SELECT COALESCE(ts.CURRVAL, ts.NEXTVAL) FROM DUAL;
SELECT NVL(ts.CURRVAL, ts.NEXTVAL) FROM DUAL;
SELECT CASE
WHEN ts.CURRVAL IS NOT NULL THEN ts.CURRVAL
ELSE ts.NEXTVAL
END
FROM DUAL;
Ideally multiple executions of any of these (or a better one of your design) should return the same value from the sequence, but mine do not.

The conditional statements should not only be executed in sequence, but also if any of them are true they should not be overridden by any subsequent conditional statements being true.
When actual effort Accepted or Rejected for AST proposals and calculate a flag for "enhance to AST guideline" = Y/N as follows for each employee and display at the employee level
1)If AST eligibility = N AND proposed AST % >0, then "N"
2)Else If AST eligibility = N AND proposed AST % = 0 then "n/a"
3)Else If AST eligibility = Y AND Act Rank = 3 AND proposed AST = 0 then "Y"
4)Else If AST eligibility = Y AND Act Rank = 3 AND proposed AST >0 then "N"
5)Else If AST eligibility = Y AND Act Rank = 2 AND proposed AST = 0 then "Y"
6)Else If AST eligibility = Y AND AST % is greater than or equal to the AST guideline minimum AND less than or equal to the AST guideline maximum, then "Y"

I tried the following code but I am not getting the expected result .

Task I would like to do in plain SQL rather than PL/SQL.
Given this table:
create table TEMP_TEST
(
DT_START DATE not null,
DT_END DATE not null,
FIELD VARCHAR2(2)
)
and these rows:
insert into temp_test (DT_START, DT_END, FIELD)
values (to_date('01-01-2005', 'dd-mm-yyyy'), to_date('31-08-2007', 'dd-mm-yyyy'), 'ML');
insert into temp_test (DT_START, DT_END, FIELD)
values (to_date('01-09-2007', 'dd-mm-yyyy'), to_date('31-12-2007', 'dd-mm-yyyy'), 'MT');
[Code]....
what i want to do is collapse the rows that have same field value, ONLY if the end date of the first one equals start date -1 of the next one.
that being said the result should be
01/01/2005 - 31/08/2007 - ML 01/09/2007 - 31/12/2007 - MT 01/01/2008 - 29/02/2012 - ML 15/03/2012 - 31/12/9999 - ML
I was doing this:
SELECT MIN(dt_start), MAX(dt_end), field
FROM(
SELECT dt_start,
dt_end,
field,
[Code]....
but it still misses the thing about adjacent time periods

I want to write a sql qeuery to get result similar to expected average column as shown in sheet.
Record can be uniquely identified by columns ID, PRODUCT and OFFICE. I want to calculate average for each date considering the same record does not exists earlier i.e. I want to consider the latest vote while calculating average. E.g.
Average till date 1/1/2011 is Avg (2, 4, 3) = 3 (as no repeating vote value exists)
Average till date 2/1/2011 is Avg (4, 3, 5, 3) = 3.75 (excluding vote value 2 as 122_UK_LONDON was provided his vote earlier, so considered latest vote value i.e. 5)
Average till date 3/1/2011 is Avg (3, 5, 3, 6, 5, 8 ) = 5 (excluding vote value 2 for 122_UK_LONDON and vote value 4 for 967_Europe_London)

So when dept.deptno=10, I want to display these 2 columns values
1. dept.deptno
2. dept.dname
otherwise, display these 2 columns values
1. dept.loc
2. null
Can this be done with one case, decode or "other" type of structure going thru the table one time??

For example please run below sql:
create table merge_test(col1 number, col2 number);
create or replace trigger merge_test_tr_stat
after INSERT OR UPDATE OR DELETE on merge_test
begin
if inserting or updating or deleting then
dbms_output.put_line('conditional predicates is working ');
else
dbms_output.put_line('conditional predicates is not working ');
end if;
end;
set serveroutput on;
insert into merge_test values (1,1);
Output
------
1 rows inserted.
conditional predicates is working
conditional predicates is working
set serveroutput on;
merge into merge_test mt using ( select 1 col1 from dual ) tab
on ( mt.col1 = tab.col1 )
when matched then
update set col2 = 2
when not matched then
insert values (1,1);
Output
